Unless it’s your job to be ‘everywhere he looks’ don’t do it.
Do your job, not the office managers.
Unless your pay rate is very low I doubt he wants you getting him coffee.
Suddenly being too helpful sends an even worse message then simply sucking up a little.
I might start showing up earlier then the boss or his snitches (you know who they are).
But if you aren’t a solid performer it’s really too late to change that now.
Really bad advice, dude.
NOT the practices of someone who wants to get ahead - just the attitude of someone who has a job he hates, barely performs and wonders why he isn’t getting anywhere.
