The management culture - some of them are very nice don't get me wrong, but many of them are so uppity, and why? Get a grip - you're a manager in a department of a supermarket, you're not a big shot or something special by any stretch of the imagination. Seems to go to their heads.
And it's not only the managers - some team leaders think they run the place!
If you work part time, depending on your hours, you're basically not allowed to be sick for more than a day a year. Disciplinary procedures, meetings and reviews if you have two days off in the space of six months.
They mess up pay WAY too much. Honestly, how can they mess up something so simple? Especially with clocking in and out! Then they make it ridiculously awkward and difficult to get it. They owed me £300 which I never got; I was asked to write down my hours, and I did this maybe 3 or 4 times, and when I queried it further - "oh too much time has passed now". It beggars belief. Especially as I KNOW that it's just a case of popping the hours into the computer. They either don't care, or can't be bothered. I expect a bit of both.
Ridiculous expectations. I worked on the home delivery department and you were expected to 'pick' at the speed of light and have 'blue/green' performance regardless of problems occasionally encountered, such as items not being on the shelves and having to trawl the warehouse to look for them. This can take a bit of time (all of 5/10 minutes) but surely it's worth finding the item the customer actually wants, even if it takes a little longer to finish? Customer is disregarded here... WORK FASTER! FASTER FASTER GO GO GO
... but unless the delivery van is revving waiting on you, which they never are, ever - I mean honestly, never ever has this happened :/ this is a complete non issue. Jobs-worth stuff for statistics that don't matter to anybody.
They can be short-staffed but won't provide the overtime, meaning the team are overworked and stressed. Home delivery often have to work beyond finish time to get finished just because they won't give other overtime. Silly.
