Kontras
As said in the title, my experiences varied greatly working for Asda depending on who my line manager was at the time. Some were very accommodating and allowed flexibility in your working days etc, others were very rigid. Taking holidays was a nightmare as you had to put in all 4 weeks of holidays at the start of the new year, with longer serving staff members getting "their" holidays every year. The overtime culture around christmas was also awful - with ALL staff expected to seriously increase the number of both hours and days that they worked, which as a part time member of staff meant essentially having to work full time when not always convenient or risk facing your manager to have a talk about you "letting down the team"
