Oh hush. No one works harder when there is a call out unless you want to. When people in the be call out, I still do the same amount of work. A cashier will check out the same amount of people and so onYeah, by all means, call out. No one will mind taking up the slack for your absence. We all love working harder so that you can enjoy your holiday.
Just remember, when you're whining about hours in a month or so, the guys taking up your slack will be getting the hours instead of you.
Call out TC. I'm sure your co-workers do it to you, and it's even outside your availability
