Labour is really tough, we are lucky that we have deep roots in the Latin community so hiring has been ok but only based on word of mouth referrals.
Tech shortage hasn't impacted us.
Part shortage is a real pain. Three months ago EGR values just disappeared off the face of the planet. Prices are fluctuating like crazy, some weeks filters are $13 while other weeks are $8.00....for example NOX sensors, right now there is a huge sale for us at $250 per sensor last month those exact same NOX sensors were $800.
