I don't recall what brands they were though.

Re: PERFORMANCE AND DEVELOPMENT PLANS

The SAM is my supervisor here. We were given the forms to fill out and pretty much left to our own devices...... Not a whole lot of support here, and if I ask I feel like I'm being a nuisance! So I wrote what I thought was relevant for me..........
