I don't agree that the professional decision is to say no when you are 1 minute over your time,
Some of the questions asked in an interview is about time. When was your last break, what time did you book on, how many hours have you had off. I remember when a friend had an incident and they were told that if they took the additional 5 minutes they were entitled to for their break instead of working through it and trying to keep their train on time, they would not have had the incident. This is the industry we work in. An industry where every single minute of your day is tracked. Booking on 11h 59mins between shifts will break Hidden. It just isn't allowed.
I don't really agree that you should discriminate against someone you don't like - but if a resource manager is all take and no give, then I can see why you would want to give less freely.
The problem that this discussion has revolved around is that when it becomes discrimination and when it is just normal human behaviour' also where your rights as an employee are. Most of my resource managers are good as gold. A few I will always go above and beyond because I have a good relationship with them. A few are outright incompetent, vindictive, and nasty. Why should I do a 'favour' for them ? If Bill is a mate of mine and has covered my shifts on a regular basis I'll happily swap with them. Should I swap with someone who never helps me out, and is a backstabbing !"£! ? If there was a letter that got sent around saying 'don't help' Jack. That would be discriminatory. I read the case where there was discrimination based on being 'ostracised' and there was a clear case of being specifically ignored and where their computer access was deliberately removed. It was very different to just not doing Jack a favour.
As I stated, by its very nature. Doing someone a favour' is discriminatory. You make a choice to swap or choice to help out. The alternative is to refuse every request the resource managers ask. That single minute I'll help out with will never happen again.
When is it 'discrimination' Its difficult to distinguish helping a mate out vs refusing to help someone else. This is where 'professionalism' comes in. If you are doing your job 100% to the letter then nobody can complain. If I single out someone in a negative way, send an email to 'all drivers' but edit out their name, then yes, that would be discrimination. If I specifically went hard on their assessment, yes, it would be discrimination. If I was doing an interview and scored them lower because I didn't like them, gave someone else a job because I didn't like someone then yep, all discrimination.
I hate swapping shifts but there are specific people I tend to swap with to help them out. Is that discrimination ?
